OLIVOPONTOCEREBELLAR ATROPHY-MRI
It is characterized by atrophy of brainstem and cerebellum, less commonly associated with supratentorial atrophy. As in our case, Atrophied Pons selectively in its lower part is well demonstrated on T1 sagittal images. On coronal T2WI, atrophy of middle cerebellar peduncles giving pointed appearance to lateral end of pons, can be seen. Signal abnormalities of transverse pontine fibres in well seen on intermediate intensity images, so better visualized on Axial PD sequences than T2 weighted image. Diffuse hyperintensity of cerebellum well appreciated on coronal sections. Basal ganglia are not commonly involved, when abnormal signal detected, putamen involved most commonly and is associated with multisystem atrophy.
